This double sprocket from MR is identified by a 3/8" pitch and 38 teeth (Z38), and it is machined from SAE 1045 steel. Two toothed rings share a single hub, so one shaft can drive two chains side by side. That arrangement keeps both chain lines synchronized, which is why it shows up in medium-duty drives where speed and pulling capacity need to be balanced. The part is built for continuous operation in industrial equipment.

The configuration is a double sprocket with a central hub. The hub gives you the bore and the mounting surface for the fastening system, while the two tooth rings let you run two chains on the same body. The 3/8" pitch means it takes roller chains of that pitch, and the 38-tooth count sets the drive ratio when paired with another sprocket. MR supplies it with dimensional checks on the toothing and the central bore.

You will find this type of sprocket in drive lines that need two branches moving at once: roller conveyors, bucket elevators, packaging machinery, material handling equipment and drag systems in process plants. It also appears in gear reducers and transmission boxes that call for two synchronized outputs. As a part from MR, it can be adapted to specific machining requirements within what the process allows.

For selection, confirm that your chain pitch matches the 3/8" pitch of the sprocket and that 38 teeth fit the ratio you need. Check the shaft diameter and the fastening method (keyway, set screws or taper bushing) before mounting. Keep sprocket and chain alignment within tolerances to avoid uneven wear. Lubrication and correct chain tension also help the toothing last.

If you are looking for an equivalent, send the complete part number of the sprocket you are replacing, along with the number of teeth, the pitch and a photo or sketch of the assembly. With that information we can identify a similar part in our product line or source a variant. We can also advise on the compatible chain and fastening accessories.
